Nitrous oxide (N2O) is an important long-lived greenhouse gas and is a dominant contributor to stratospheric ozone depletion. Mitigating N2O emission from the rice paddies is one of the important challenges to global food security and climate change research while sustaining optimum productivity. We conducted a 2-year experiment to investigate the effect of different plant growth regulators (PGRs) on N2O emission to the atmosphere. The PGRs namely abscisic acid and cytozyme (20 mg L−1), kinetin (10 and 20 mg L−1) and tea extract (1:20 w/w) along with distilled water as control were sprayed at the tillering and panicle initiation stages of rice crop. Abscisic acid and kinetin (10 and 20 mg L−1) were found to bring about a significant (p
